V SPECIFICATION forming part of Letters Patent No. 437,337, dated September 30, 1890.

Application filed April 17, 1890-: Serial No. 348,368. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM J. HALL, of. New York city, in the county and State of New York, have invented a new and useful Improvement in Car-Window Sashes, which improvement is fully set forth in the following specification.

This invention has reference to the construction of window-sashes for use particularly on cars, stages, omnibuses, and other ve-' hicles, also on all conveyances for land and water, but applicable also to houses and other buildings, and has for its primary obj ect to suppress the rattling noise produced by the shaking of the glass and sash when the vehicle is in motion and to diminish the liability of breakage from the same cause. The invention maybe regarded as an improvement upon that described and claimed in my patent, No. 220,756, dated October 21, 1879, for a sashframe made wholly of rubber. There are certain inconveniences or disadvantages attending the construction and use of frames composed wholly of rubber; and it is a further object of this invention to avoid these and to produce a practical, simple, and efficient device for the purposes above specified.

In carrying out the present invention I employ a grooved rubber strip or strips surrounding the glass on all" four sides. These strips do not constitute the sash-frame, but lie in a' frame of wood, which is rabbeted out to receive the strips. The latter are retained in place by a metal face-plate or wooden molding screwed or otherwise attached to the main sash-frame. The rubber strips are thus more accessible for repair than when held in metal stiles of channel-bar form, as heretofore proposed. For the purpose of giving access to the glass for insertion and removal, one part of the sash (preferably the top) is made detachable, so that it can be quickly taken off and replaced when necessary. The rubber strips are made with grooves having a dovetail or similar form in cross-section, so that the outer edges of the strip press upon the glass, holding it securely and preventing water, dust, or other foreign matter from getting into the groove.

In the accompanying drawings, which form part of this specification, Figure I is a front elevation of a car-window sash constructed in accordance with this invention, showing the top rail of the window detached. Fig. II is a cross-section on line II II, but showing a fiat metal plate in place of a'molding, as in Fig. I; and Fig. 1H, detail views on an enlarged scale.

In Fig. I, A represents the glass pane, B the side bars or stiles, O the top, and D the bottom, of the sash.

The glass is surrounded on all four edges by grooved rubber strips a, forming a contin uous frame of rubber. This is the best embodiment of the invention; but it will be understood that practical results can be secured by using strips that extend along portions only of the four sides. over, the glass will be less effectively protected against injury. These strips may be of softer and more elastic rubber than when the entire sash-frame is of rubber.

In applying the strips a the main portion of the frame is cut out to form a seat (see Fig. II) of the size and shape to receive the rubber strips, which are held in place by strips of molding E, as in Fig. I, or by metal plates F, as in Fig. II, secured by fastening-screws e, permitting ready access to the rubber strips when desired. The plate F shown in Fig. II is the equivalent of themolding E of Fig. I,

the only difference being that the former has a plain outer surface. The groove in strips a, as shown in Fig. II, is of dovetail form in cross-section, so that the rubber flanges when compressed between the frame B and holdingstrip E or F, which latter completely covers the rubber strip, press firmly upon the glass .A, holding it securely, and excluding all dust,

Water, and other foreign matter from the groove. The holding-strip E or F also serves to protect the outer surface of strip a fromaexposure.

To facilitate the insertion and removal of the glass, the top rail 0 (or it may be one of the other sides) is made detachable, being fitted to the side bars B by tenons and mortises and secured by fastening-plates f (shown in Fig. I) or by other suitable means.

The edges of the side bars B are provided with one or more small rubber rollers gin the shape of disks. These are preferably cut from material such as used in the manufacture of In such case, howpacking-that is, a stock composed of alternate layers of rubber and fibrous material or molded from the pure rubber itself. The disks are placed in countersunk grooves in the bars 13 so as not to project above the edge thereof, and are held by screw-pins h, which pass centrally through the rollers.

To reduce friction in rotating, the rollers may have a metal eye k; but this may be dispensed with. I

In order that the heads of screws h may not project beyond the plane of the edge of the bar B, the outside face of the rubber disk may have a countersunk recess to receive the heads, as shown in Fig. II; but the same result may be accomplished by simply making the groove or recess in the barB sufficiently deep to lower the head of the screw beneath its surface.

The diameter of the rubber disks 9 is such that they project for a short distance beyond the bars B on each side. Thus the same disk serves as a pad or cushion on both front and back of the sash and acts more efficiently than two disks placed on the stationary art of the window-frame on opposite sides 0 the sash.

Having now fully described my said invention, what I claim, and desire to secure by Letters Patent, is

In a window-sash for vehicles or buildings, the combination of the pane of glass, the wooden sash-frame rabbeted out to form a recess around its inner edge, grooved rubber strips surrounding the four sides of the glass and filling said recess, plates or moldings screwed to the'frame and covering said rubber strips, one of the sides of the frame, with the attached molding or plate and rubber strip,

being removable, and the fastening-plates f,

substantially as described. p

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
